The
visualization of events registered in NUCLEON SSC is a part of rapid analysis
of scientific information and aims to simplify the evaluation of input data. Visualization
is carried out with the DrawEvent program. Each event has its own a so-called
"Portrait of event” based on the results of this software. On the
"portrait" in the upper left corner are shown all 4 planes of ChMS with the overlap. Different planes correspond to
different colors. For understanding of what colors correspond to planes, you
should look at the images of the same planes on the XZ and YZ side projections
of devices. The circles show the triggered pads, and the area of the circle is proportional to the effective
charge measured by this pad. The maximum charge value corresponding to the
largest circle can be seen on the information panel. Jumper between the pads in
the form of segments connect pads that respond to the same electronic channel.
The XZ and YZ side projections of the deviceare shown below and to the right of
the ChMS. The amplitudes of all signals are shown in a
relative color scale on the lateral projections. Black indicates non-working
channels.
The
histograms for energy emissions along various planes of SFTS (td), KLEM system tracker (s)
and MIC
(m) detectors are displayed
in the right part of the figure. The leftmost group of 9 histograms is the X
orientation planes (from top to bottom - td0, s0.2, td2, s4, td4, m0,2,4); the
rightmost group of 9 histograms - the Y orientation plane (from top to bottom -
td1, s1, td3, s3,5, td5, m1,3,5). Each channel is shown separately. The
amplitudes are given in (m) units. (m) is an energy release of a single-charged
relativistic particle. Three cascade curves are under the information panel.
The longitudinal development of cascades for (td), (s) and (m) is apart. The
vertical scale in the cascade curves is compiled. Each bar of the cascade
curves histograms is proportional to the full energy release in the layer in
(m) units. Various types of detectors correspond to different scale along the
energy axis. The reconstructed shower axis is shown on the side projections of
device. The dotted crosshair on ChMS plane shows the exit point of the axis to the ChMS upper
plane.
In
the (s) and (m), the picture on the strips is enlarged by summing the signals
into groups of neighboring strips: 8 for (s) and 4 for (m). It is because of
insufficient computer screen resolution. Each non-working strip is shown
separately.
